Try to think of your problem in two parts.  Think about the pure
Python business logic first.  That should dictate most of the
structure of the Python code.  Next think about how you want to
present your business objects to the user.  This will determine what
HTML pages you need in your web application.

Try to keep a clean separation between the implementation of the
business logic and the presentation layer.  The more complex your
application the more important it will be to have a clean interface.

By placing the business logic in pure Python you will be able to test
the code without having to sit in front of a browser.

Start small by thinking of a simple part of the application which you
can code quickly.  Try building that portion of the application using
Albatross.  You will learn only by trying and making mistakes.

This stuff is quite mind bending.  Once you have some things going you
will find the rest starts fall into place.

I imagine that you have a model in your head but are having trouble
trying to attach Albatross to that model.  The best way to break the
log jam is to use Albatross on a trivial problem to let Albatross
become one of the mental constructs that you can push around in your
head.

Lewis> The docs and examples are great but being new to python and
Lewis> albatross is overwhelming me at the moment.

Start small and simple and build your knowledge slowly.
